Leaky‐Integrate‐Fire Neuron via Synthetic Antiferromagnetic Coupling and Spin‐Orbit Torque

Advanced Science, EarlyView.
A spintronic leaky‐integrate‐and‐fire neuron is realized using Spin Orbit Torque driven domain‐wall motion for integration and synthetic antiferromagnetic coupling for the leaky process. The specialized Hall‐bar geometry enables controlled DW dynamics, achieving repeatable integration and firing events. This compact, CMOS‐compatible design highlights a

Beyond Cocrystals: Hierarchical Functional Assemblies via Noncovalent Synthesis

Advanced Science, EarlyView.
Non‐covalent interactions (NCIs) drive the formation of organic cocrystals with diverse structures and tunable optoelectronic properties. This review explores the essential factors governing these properties, highlighting how the sequential nucleation of cocrystals leads to the self‐assembly of organic hierarchical structures (OHSs).
